A method and apparatus for determining the contact angle of a droplet of test liquid on a substrate surface. The apparatus includes a test article support plate, a pipette for depositing a droplet of test liquid onto a substrate surface of the test article, and a lamp for projecting an image of the deposited droplet onto a projection screen with a base line of the image positioned on a horizontal axis line of the screen. The screen further has a protractor scale calibrated to read twice the normal angular value, and a rotatable reference line which upon positioning through a contact point of the droplet with the substrate surface and an apex point of the droplet farthest removed from the substrate surface directly indicates the value of the contact angle of the on the protractor scale.

An apparatus for treating the surfaces of formed plastic articles including a plurality of bare metal discharge electrodes connected to a high frequency AC power supply, a counterelectrode disposed in spaced relation to the discharge electrodes for defining a treatment zone therebetween, and an insulation layer mounted in spaced relation to the counterelectrode such that a discreet air space exists between the insulation and counterelectrode for moderating the electrical discharge between the discharge electrodes and counterelectrode and enabling greater control and uniformity in the electrical discharge between the electrodes and counterelectrodes. In the illustrated the embodiment, a first set of discharge electrodes define a first treatment zone for treating one-half of the circumferential surface of articles directed through the first treatment zone and a second set of discharge electrodes define a second treatment zone for an treating opposite peripheral half of the circumferential surface of articles passing through the second treatment zone.

A tire having a section height, a maximum section width, an upper section above the maximum section width, and a lower section below the maximum section width is provided. The tire includes a circumferential tread, a pair of sidewalls, a pair of bead regions each having a bead core, and at least one carcass ply extending circumferentially about the tire from one bead region to the other. The at least one carcass ply is wound outwardly about at least one of the bead cores and extends toward the tread to form a turn-up portion that terminates at a turn-up end. The turn-up portion includes a concave segment that begins in the bead region and ends short of the turn-up end or at the turn-up end.

A pneumatic tire may include a floating reinforcing layer disposed between a body ply and the sidewall of the tire. The reinforcing layer may extend from a point beneath the rim flange of the wheel to a point just above or below the maximum section width of the tire. By adding stiffness to the sidewall region at and above the rim, the reinforcing layer enhances the durability of tire without sacrificing ride comfort.
摘要:
A camera assembly including first and second rotating members and a motor assembly defining a first axis and operably coupled to first rotating member to drivingly rotate first rotating member. A flexible member operably couples first and second rotating members such that rotation of first rotating member causes rotation of second rotating member. A camera is operably coupled to second rotating member such that rotation of second rotating member repositions camera. The motor assembly includes a flange having an outer circumference defining a plurality of teeth and bearing against a support surface. The outer circumference defines a radially variable distance from first axis such that rotation of outer circumference against support surface displaces first axis relative to second rotational member and thereby adjusts a tensional force in flexible member. At least one pawl mechanism is fixed relative to support surface and is engageable with outer circumference.

A cap to close off an externally threaded aperture of a container is provided. The cap includes a base wall and a peripheral skirt carrying an internal thread for mating with the aperture's external thread. A hollow spigot portion extends from the base wall within the cap, and is co-axial with the skirt and attached to the base wall by a frangible connection. Grooves or thread are formed on the outside wall of the spigot portion to engage the wall of the bore in the aperture. A method of sealing a container including engaging a cap is also provided.

Methods, systems and program products for providing a first visual region, the first visual region configured to present content determined by a document. A distinct second visual region is provided, the second visual region not defined by the document and configured to present content that is not contained in the document. One or more attributes are identified in the electronic document. Based on the one or more attributes, the presentation of ad content in the second visual region is enabled or disabled. The electronic document is presented in the first visual region.
摘要:
Methods, computer program products and systems for accessing an electronic document, the electronic document including embedded content, where the file type of the electronic document differs from the file type of the embedded content. The embedded content is provided to a first rendering engine in accordance with the embedded content file type. Rendered embedded content is received from the first rendering engine. The rendered embedded content is blended with a rendering of a page of the electronic document.
摘要:
A camera system having a camera lens module, a slip ring connector, and a pan/tilt mechanism. In one construction, the camera system includes a circuit board, a slip ring having a stator connected to the circuit board and a rotor rotatable with respect to the stator, a camera lens module, and a flexible flat cable. The camera system can also include an anti-rotation arm connected to the rotor and in contact with a first end of the flexible flat cable. The anti-rotation arm can prevent a twist of the flexible flat cable during panning of the camera lens module.
